Can someone help me with this question pls and thank you

Answer:

a) The maximum height that the ball reaches is 73.1 meter

b ) The time elapsed when the ball reaches its maximum height of flight = 2.2 seconds

Step-by-step explanation:

The complete question is

During a high school baseball tournament, Lando hits a pitch and the baseball stays in the air for 4.42 seconds. The function h(t) = -5t2 + 22t + 0.5 describes the height over time, where h is its height, in meters, and t is the time, in seconds, from the instant the ball is hit. a. What is the maximum height the ball reaches? b. What will be the time elapsed when the ball reaches its maximum height of flight?

Solution:

For maximum height

[tex]\frac{dh}{dt} =0[/tex]

[tex]\frac{d(5t^2 + 22t + 0.5)}{dt}\\ 10t + 22 = 0\\t = 2.2[/tex]seconds

a) Maximum height

[tex]5 * t^2 + 22t + 0.5[/tex]

[tex]= 5 * 2.2 *2.2 + 22 * 2.2 + 0.5 \\= 73.1[/tex]

b) Time elapsed when the ball reaches maximum height is 2.2 seconds

Answer:

The measure of the largest triangle is 72.

Step-by-step explanation:

Set up an equation to find the angle. note that angles in a triangle sum to 180.

With this information, we can set up an equation:

24x + 21x + 15x = 180

(add the x terms)

60x = 180

(divide both sides by 60)

x = 3

We now know what x equals. Now, we can multiply 3 by the largest angle of all- 24.

24 * 3 = 60.

Hope this helps.

This is a linear relationship.

Linear relationship is a statistical term used to describe a straight-line relationship between two variables. These two equations are written in the typical slope-intercept form of y = mx + c, this function creates a straight line when plotted.

Answer:

the last one (-14)+(-8)

Step-by-step explanation:

-14 - -8 any time you have minus a negative it's a + sign

so

-14+8 therefore it's the first one.

Answer:

y=5/4x-8

Step-by-step explanation:

Answer:

[see below]

Step-by-step explanation:

General Point Slope Form is:

[tex]y-y_1=m(x-x_1)\\\\\rightarrow \text{m - slope}\\\\\rightarrow (x_1,y_1)\text{ - given point}[/tex]

We are given the slope of (5/4) and the point of (8, -2).

Replace the variables with their appropriate values:

[tex]x_1 \rightarrow8\\\\y_1\rightarrow-2\\\\m\rightarrow\frac{5}{4}\\\\\text{Replace } x_1, y_1, \text{and } m \text{ with the appropriate values.}\\\\y-y_1=m(x-x_1)\rightarrow y-(-2)=\frac{5}{4}(x-8)\\\\\text{Simplify:}\\\\y-(-2)=\frac{5}{4}(x-8)\rightarrow y+2=\frac{5}{4}(x-8)\\\\\\\text{Our final answer is:}\\\\ \huge\boxed{y+2=\frac{5}{4}(x-8)}[/tex]

Hope this helps.

A mixed number is an addition of its whole and fractional parts.

Addition 2 + 2/3

Improper Fraction: 8/3

Decimal Form: 2.(6 recurring)

Mixed Number Form: 2 and 2/3

Answer: 20 miles

Step-by-step explanation:

From the question, we are informed that Avis truck company charges $20 plus $2 per mile and that Budget truck company charges $3 per mile.

Let the number of miles that the charge will be the same for both companies be represented by x. This can then be used to form an equation as:

20 + 2x = (3 × x)

20 + 2x = 3x

3x - 2x = 20

x = 20

The charge will be thesame at 20 miles

Step-by-step explanation:

When dealing with graphs, involving points in between numbers, we have to carefully look at the x and y axis.

On the graph, the y-axis is going by 2s: 0, 2, 4, 6, 8, 10

On the x-axis, it's going by 1s: 0, 1, 2, 3, 4, 5, 6

Between 2 and 4 is 3

Between 4 and 6 is 5

Between 6 and 8 is 7

Between 8 and 10 is 9

Between 2 and 3 is 2.5

Between 3 and 4 is 3.5

Between 4 and 5 is 4.5

Between 5 and 6 is 5.5

Between 6 and 7 is 6.5

Between 7 and 8 is 8.5

Between 8 and 9 is 8.5

Between 9 and 10 is 9.5

Between 10 and 11 is 10.5

You get to see the pattern going on here...

On point E, we can see that the x-axis is 2.

Now on the y-axis, it is between 6 and 7. But if you look closely, you'll see that it's not on the line, that indicates 6.5.

So we find the median...

6, 6.1, 6.2, 6.3, 6.4, 6.5    6.2 and 6.3 are on the medium

           [tex]\frac{6.2 + 6.3}{2}[/tex] = 6.25    Answer on E: (2, 6.25)

On point F, we can see that the x-axis is 3.

On the y-axis, it is between 8 and 10, which would be 9, BUT, look closely that it's also between 9 and 9.5.

The answer would be 9.5, but it is SLIGHTLY below 9.5, so I think it's 9.4

Answer on F: (3, 9.4)

On point G, the x-axis is between 3 and 4, so it's 3.5.

On the y-axis, we know it's going by 2s. We can see that G is between 10 and 12, so it would be 11. Because it is on that thin line, as you can see.

Answer on G: (3.5, 11)

Answer:

a.

Step-by-step explanation:

this is a y = mx + b equation

the “B” is the y-intercept. So look where the line crosses the 6 axis. The equation says -1. Right away, there are only two answers that could possibly be it. A and B. The Lines both cross at -1 on the y-axis.

the ”mx“ part of the equation is the slope. Slope is the change in y over the Change in x.

in other words:

y1-y2

———

x1-x2

another thing is that slope in this equation is negative. This means the line is decreasing or going/pointing down. The only possible answer is a.
